The coolant pump is a centrifugal pump used to circulate the coolant through the coolant passages and into the radiator. The coolant pump is sometimes called the water pump. The pump has a housing with coolant passages. A shaft in the middle of the pump housing is suppoted on a bearing so that it is free to rotate. When the engine is running, a belt or gear drives the shaft. The shaft drives an impeller with curved blades. As the impeller spins, a low pressure is created in the center of the impeller. The low pressure draws in collant. Centrifugal force causes the coolant to be thrown off the tip of the blades under pressure. The pump circulates the coolant through the cooling system. Coolant is pumped from the bottom tank of the radiator. It goes into the engine, the cylinder, and the cylinder head. After circulating around the coolant passages, coolant enters the radiator upper tank.

Coolant testing is vital to maintain the coolant at the specific levels for optimum machining performance, tool life and coolant life. This testing is required to determine the additive concentration and glycol level of the coolant. This will make sure that adequate liner pitting and freeze point protection are achieved. This testing is also required to determine if the coolant must be replaced due to contamination.

Coolant Unions features precision ball bearings, hardened stainless steel rotor, optimized seal balance ratio for minimal friction and standard seal face available in carbon graphite. It is designed for air, coolant and hydraulic oil.

Coolant valve is ideal for use in coolant system of the machine tools and parts wash machines and comply with RoHS directive. They offer an extremely high coefficient of volume flow (Cv) up to 18.3 with operating pressure ranging from 72psi to 232 psi. Some coolant valves has optional auto switches to confirm valve opening and closing and also to interlock with the machine tool controls.

A cooler is an insulated box, used to keep food or drink cool. Ice cubes are most commonly put in on top of the items, filling in between them. Ice packs are sometimes used, as they either contain the melting water inside, or have a gel sealed inside that also stays cold longer than plain water. Coolers are often taken on picnics, and on vacation or holiday. Where summers are hot, they may also be used just for getting cold groceries home from the store, such as keeping ice cream from melting in a hot car. Even without adding ice, this can be a big help, particularly if having to make another brief stop on the way home.
